I need to drill a couple of holes in the bottom of a kitchen cabinet to fit it with IKEA Akurum legs. I thought of using a 1/2" spade drill bit but its' narrow end – the tip of the spear so to speak – protrudes too far and would drill through the 3/4" board before the 1/2" diameter cylinder could reach 1/2" depth.
How can I drill a 1/2“ diameter, 1/2” deep hole in 3/4″ particle board

Best Answer
Carefully chop the posts on the Akrum down by 1/4" using a band saw or a dremel. Now drill a 3/8ths deep 1/2" hole using either a twist drill or a spade drill. Dip the Akrum in a bit of epoxy or wood glue and install it. This will provide the same centering and strength, but will minimize the likelihood of drilling through the cabinet, or (worst-case) of making the hole too short and having the weight of the cabinet fall on the post rather than on the rectangular structure around it.
As a practical concern, given the comments that you made, it doesn't seem that if you drill the hole all the way through anything bad will happen, except that you'll have some surface imperfections on the floor of the cabinet.
